Non-migrating plasticizers – All types of plastic contain oils or “plasticizers.” These oils are usually free to move around within the plastic. They will migrate to the surface where they can be washed away, or the plasticizers will migrate to the bottom of the material and compromise the glue bond.The oils in our PVC plastic will not migrate because the oils are locked in place. That means that the PlasDECK won’t dry out, crack, or crumble over time and the PlasDECK will retain its superior adhesion. This proprietary process is unique to PlasDECK decking material and can’t be found in other synthetic decking products on the market. We have been awarded two US Patents (US Patents 7,578,251 & 7,617,791).These samples represent 500, 1000, 1500, 2000, 2500 hour exposures (i.e. 500 = 1 year, 2500 = 5 Year). The conditions of the test were 16 hours of UV light at 158ºF (70ºC), followed by 8 hours condensation at 122ºF (50ºC).Below are the actual samples that were tested. As you can see, the color remained intact and there are no signs of any degradation in the material.
